Yes, K2 will work with a RS232 to USB cable available at a computer shop. I got mine locally at US$15.

Yes, I built the Elecraft cable with the I/O kit and used
a FTDI chipset serial to usb cable with it with no issues. Use it often on digital modes. Prolific chipset serial to usb cable did not work. I did not investigate why just changed to a FTDI cable.

I'm writing this because Joe was not DIRE enough. Try this. You should
feel the air rushing past your ears.... \Screaming mode on\ Be careful. The DB9 socket on the back of the K2 is ***** NOT ***** RS232. It's proprietary. Pins 1, 4, 6,7,8 are used for proprietary purposes and it's possible you can ***** SMOKE ***** your computer or K2. You ***** MUST ***** use the method in your manual or its equivalent to split off ***** ONLY ***** 2, 3, 5 for RS232 use. ***** YOU HAVE BEEN WARNED ***** \Screaming mode off\ Some people have gone so far to plug up one hole in the socket so a regular DB9 male plug simply can't be inserted accidentally. Some years ago, when the KIO2 was new, there was a regular smoke-em parade of those who had ignored the admonishment and burned something up. Some folks did it two or three times. In WWII the military solved this ghastly problem by having a gazillion multi-pin plug and socket layouts, so you could ONLY plug something in where it actually matched up wire for wire. If your dog could get the plug in on his own it was right. No doubt saved a few lives. 73, Guy.

No it definitely isn't and you gotta read the manual, it's pretty explicit about this. > In WWII the military solved this ghastly problem by having a gazillion > multi-pin plug and socket layouts, so you could ONLY plug something in > where it actually matched up wire for wire.

Alas, my friend Leo Endres, engineer and philosopher was right when he said, "The problem with Lessons Learned is -- they rarely are." A well known USAF stealth airplane of moderately recent vintage, which really didn't want to fly and, left to its own devices, had the glide angle of a brick, so it was totally dependent on its electronic stabilization systems. Even moving on the ground, the control surfaces were constantly correcting. Unfortunately, it did allow [at first] the pitch and roll gyros to be misconnected which happened once to my knowledge. Scream down the runway, pull the stick back, turn over inverted and ... land. Pilot walked away, thank God. This situation also exists inside the K2, the 12VDC and RF connectors to the KAT2 or KAT100 if they're there, will gladly interconnect with not great results. All it takes is some real care when you're doing things in there, sort of like paying attention when you're driving. Try not to have a glass of wine or a beer with dinner before working on your radio. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
